2.
Site Tour The IE inspector walked through the Reactor and Auxiliary Buildings to observe construction activities in progress and to inspect for housekeeping.
I No violations or deviations were identified.
3.
Safety-Related Electrical Cable Terminations The IE inspector observed various stages of in-process cable terminations, completed cable terminations, and the documentation and inspection records associated with these terminations to determine compliance with FSAR commitments, craft and Quality Control procedures, design drawings, and industry (IEEE & IPCEA) standards.
The following completed terminations were inspected and the associated documents were reviewed to determine continuity from design drawing to.
actual termination including documentation which had been accomplished:
323598-SB 303378-SB 32397B-SA 30526A-SB 30500B-SA 310418-SA 30535A-SB 30170S-SB 31005E-SA 324808-SA 30189G-SMB 310050-SA 30188G-SMA 30541B-SB 20538E-SB-2-J
_)
.
The IE inspector also witnessed portions of the in-process installation of stress cones for the termination of cables 323778-SB, 32377C-SB and the hy-pot testing of cable 32397B-SB.
No violations or deviations were identified.
4.
Electrical Penetration Assemblies (EPA)
During the course of the inspection, the IE inspector observed that the EPAs did not have any indicated seal pressure on the primary or secondary seals.
The licensee representative advised the IE inspector that problems had developed in maintaining seal pressure and all of the EPAs were under-going modifications to correct the problem.
A subsequent review of Ebasco NCR W3-1755, Supplement 3 indicated that the pressure was leaking through the Lee Plugs and that the final solution to the problem was to seat the Lee Plugs and weld them into place.
The welding on the primary seal is in accordance with ASME Section III and the welding on the secondary seal is in accordance with AWS Dl.1 as required by Ebasco Field Change Request FCR-E-845 to Ebasco Drawing LOU 1564 B-136, Sheets 4 and 5.
The EPAs were originally fabricated to ASME Section III and the original installation was to ASME Section III, Subsection NE (Class MC) for the primary side and AWS Dl.1,1975 for the secondary side.
The FSAR comitments address ASME only and the manufacturer only addresses ASME.
The IE inspector was unable to determine if AWS Dl.1,1975 was an appropriate welding code versus ASME for the original installation or the subsequent repair authorized by NCR W3-1755.
The IE inspector was also unable to determine if AWS D1.1,1975 and CP-407, weld procedure used for providing the seal type plug weld on the Lee Plugs, were the appropriate Code and procedure.
The licensee representative has agreed to provide the IE inspector with further information from Ebasco related to the safety implications of the secondary seal and information from Conax on AWS welding on Lee Plugs and secondary header on the ASME "N" stamped EPAs.
This matter is considered unresolved pending the required information in the preceding oaragraoh.
5.
Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, violations or deviations. One item relating to electrical penetration assemblies is identified in paragraph 4.
